A Gainsborough man has been sentenced to 15 years in prison for two charges of rape and five of sexual assault.
Lee Schofield appeared at Lincoln Crown Court on Thursday 10th April.
The court heard how he used alcohol to render his victim unconscious before raping her on a number of occasions.
His horrific acts came to light when DVDs were found showing graphic footage of the offences.
DC David Patten of the Lincolnshire Police Emerald Team was the investigating officer.
He said: “This is one of the worst cases we have dealt with.”
“The offending took place without the knowledge of the victim.”
“When she found out about what she had been subjected to she was understandably horrified.”
“The 15 year sentence reflects the horrendous nature of the crimes.”
“It’s reassuring to know that Schofield will be behind bars for a very long time.”
